the main character is a pink haired girl. she uses a hammer as a weapon. from what i saw in my Megami magazines, its based on a game.(PC i think) the OVA has 2 episodes if i recall correctly.
MC's outfit has a similar color scheme to Nanoha's.(agaian, IIRC.)
sadly, i can't recall any details about her mecha.

I had this VHS tape in the very early nineties. American version. There was an anime (possibly be an episode). The only thing I remember were mecha (not really giant), which landed on some planet I think. These also maybe fighter spacecraft, but I think those were robots.
The pilot was a young guy.
The robot has a very peculiar power source - there were some huge, long shaped minerals, which they harvested and pushed into tube-like fuel compartments.
These mechas also had peculiar control. In the cockpit, threre was a piano-like keyboard, but without black keys. The pilot pressed those keys and the keys glowed in acknoledgement.

There's an official identify this show thread like 4 threads above this one.

Heavy Metal L-Gaim OVA III has a character that pilots his mecha by playing a keyboard inside the cockpit. Been quite a while since I've seen it though so can't recall if it corresponds with the rest of the features you mentioned.

MAHQ Staff - Dunbine, L-Gaim, Escaflowne, Ideon, Gasaraki, The Big O, Overman King Gainer, Zambot 3 and FLCLIn my search for justice, I created war. In my search for war, I created death. In my search for death... I have lost my soul.

I've asked about what this is some years ago and no one knew of it back then, but what the hell...

Feature length, all-CGI (maybe by I.G?), before 2008
Future setting, not on Earth
Protagonist is a girl, adopted by a black ops veteran/retired general?
Her city turns into a giant robot in the end to fight another robot
There used to be a war between "new" and "old" humans, one side is presumed to be wiped out
Troopers in ful body armor, carry really large rifles (but apparently you can use it without the armor), no mobile suits are around
Features a vertical shaft climing scene before the robots are activated

It had this kid yelling out something and a Giant Robot would appear in the sky.
The kid would then be absorbed in the Mecha's chest plate, which had a tiny circular disc.
Occasionally the kid would also come out on the robot's palm while he flew.

like everyone else i saw this mecha anime when i was very young, i think around the mid-late 90s
what i remember is:

the main character, a boy around mid teens seems to be on his own quite a bit. no friends of such that i remember

one night he runs to a large hill (not quite big enough to be a mountain as such but big enough to hide a mecha) but i dont remember why. think there was a storm or raining quite hard too

something happens (rockslide/landslide) on the hillside to reveal a small part of the mecha, a glass like sphere on its chest. The sphere is the entry point but it doesnt open, instead it absorbs the pilot into the mecha

the boy comes back to the mecha for the next couple of days and goes into the sphere before accidently being able to move it because of an incoming threat.

threat is human based, military/organisation and not aliens.

i cant be sure about this bit but i believe it was almost like a gundam style looking mecha. the picture quality and design of the show is also later than gundam wing

it was in english dubbed that i saw on tv, most likely cartoon network as thats all i used to watch things on

other than that i only saw a couple of episodes but was in to it, not sure what happened or why i didnt see more of it.

In around 2003 or 2004, there was an anime that aired on Animax in India.

It was about a girl who had a sword, and was able to call a dragon like a light from the sky, which she used to bring up a mecha. All the fights were mecha fights. The mecha was able to transform into various elemental forms.

There was a cat like Meowth from Pokémon, which sacrificed itself in a episode to give a new transformation to the robot.

The characters were preteen or teen, and the story was set in future. The girls used to stand atop a structure like Snake Way (from DBZ).

After the show's run ended, it was replaced by The Adventures of T-Rex.

Thank you for your effort. Unfortunately this show is not what I'm looking for.
